When I see a good review, I check other reviews of this person. If there are none or very few, it's a major red flag. If there are also positive, they're not necessarily fake, but maybe this person has very low expectations overall. I imagine someone like the Alec Baldwin character in an episode of "Friends". Of course relying on this isn't fool-proof, the reviewer could be mixing their genuine, "private" reviews with the ones they get paid for, but it's something.
